A speciality of the RTEMS build system was the make preinstall step. It
copied header files from arbitrary locations into the build tree. The
header files were included via the -Bsome/build/tree/path GCC command
line option.
This has at least seven problems:
* The make preinstall step itself needs time and disk space.
* Errors in header files show up in the build tree copy. This makes it
hard for editors to open the right file to fix the error.
* There is no clear relationship between source and build tree header
files. This makes an audit of the build process difficult.
* The visibility of all header files in the build tree makes it
difficult to enforce API barriers. For example it is discouraged to
use BSP-specifics in the cpukit.
* An introduction of a new build system is difficult.
* Include paths specified by the -B option are system headers. This
may suppress warnings.
* The parallel build had sporadic failures on some hosts.
This patch removes the make preinstall step. All installed header
files are moved to dedicated include directories in the source tree.
Let @RTEMS_CPU@ be the target architecture, e.g. arm, powerpc, sparc,
etc. Let @RTEMS_BSP_FAMILIY@ be a BSP family base directory, e.g.
erc32, imx, qoriq, etc.
The new cpukit include directories are:
* cpukit/include
* cpukit/score/cpu/@RTEMS_CPU@/include
* cpukit/libnetworking
The new BSP include directories are:
* bsps/include
* bsps/@RTEMS_CPU@/include
* bsps/@RTEMS_CPU@/@RTEMS_BSP_FAMILIY@/include
There are build tree include directories for generated files.
The include directory order favours the most general header file, e.g.
it is not possible to override general header files via the include path
order.
The "bootstrap -p" option was removed. The new "bootstrap -H" option
should be used to regenerate the "headers.am" files.

This fixes the legacy Makefile based build system which expects
RTEMS_API to be identical to the tool chain version.
Update #3220.

Tool name will be "rtems5", e.g. arm-rtems5-gcc.
Next release will 5.1.0. Branch version after release will be 5.1.1.
Next master will be 6.0.0.

* Use #ifdefs for 32/64 bit code
* Use unsigned long which is 32-bit on riscv32 and 64-bit on riscv64 (register size)
* Move the code to a new shared riscv folder to be shared between riscv32 and riscv64
* Rename RTEMS_CPU extracted from command line to shared riscv target s/riscv*/riscv

We always build a C++ compiler and building with C++ does not effect
RTEMS or the runtime. This patch always enabled the support. There is
no need to manually enable it any more.
You can disable C++ with '--disable-cxx'.
If an architecture does not have a C++ compiler support is automatically
disabled.

Script does what is expected and tries to do it as
smartly as possible.
+ remove occurrences of two blank comment lines
next to each other after Id string line removed.
+ remove entire comment blocks which only exited to
contain CVS Ids
+ If the processing left a blank line at the top of
a file, it was removed.
